Review on Ultramax 1000 by Ewa Brzezina ᠌

This is my first external, before that I only used internal filters. The standard lid for the aquarium did not have technological holes for the tubes. Therefore, I had to cut the cover, but this is already a method of installation. A filter was introduced - super, if the internal one was constantly buzzing, then this is simply not audible at all. I recommend!
